The Behavior of Core Wall in Tall Buildings Capable of Two Hinges

Tall buildings with Cor wall are growing in the structural industry. Generally, occurring one plastic hinge in the base of the structure is acceptable. In this research,20, 30 and 40 story buildings are designed according to the practice and response spectrum analysis. Then, the base of the structur...
